Sunscreen is a crucial component of skincare routines, providing protection against harmful UV radiation. Over the years, advancements have been made to enhance the effectiveness of sunscreens. One such innovation is the addition of polyglutamic acid (PGA). This article will explore the benefits of

A polymer (/ˈpɒlɪmər/;[4][5] Greek poly-, "many" + -mer, "part") is a substance or material consisting of very large molecules called macromolecules, consisting of many repeating subunits. [6] Due to their wide range of properties,[7] synthetic and natural polymers play important and ubiquitous role

Polyglutamic acid (PGA) is a polymer of the amino acid glutamic acid (GA). Gamma PGA (poly-gamma-glutamic acid, γ-PGA)—a form in which the peptide bond is located between the amino group of GA and the carboxyl group at the end of the side chain of GA—is the main component of the Japanese food natto.

The polyglutamic acid molecule has been known for more than 80 years. But researchers continue to explore its many potential benefits.The study shows that polyglutamic acid is composed of chains of the amino acid glutamic acid and is produced by several Bacillus bacteria through fermentation.
